The project code is written in C++ (interface on Qt) and is distributed under the GPLv3 license. LibrePCB includes: Project management interface; Schematic editor; Multi-layer PCB editor with cloning support […]
The Linux-Hardware.org project has published statistics on hardware used in Linux over the past five years. The study involved users who uploaded hardware samples during this period using the hw-probe program. The results correlate with the yearly Ubuntu User Statistics report from Canonical. Despite the fact that in most parameters, the statistics from Canonical and Linux-Hardware.org differ within 10 […]
After two and a half years of development, the release of emulator Bochs 2.6.10 has been announced. Bochs supports CPU emulation based on x86 architecture, from i386 to current x86-64 models of Intel and AMD processors, including the emulation of various processor extensions (VMX, SSE, AES, AVX, SMP, etc.), standard input/output devices, and peripherals (emulating video cards, sound cards, Ethernet, USB, etc.).

The theory of 'management' has greatly succeeded in analyzing leadership behavior, studying the reasons for their successes and failures, and systematizing knowledge on how to develop strong qualities in themselves and combat weak ones. Foreign theorists receive particular attention from us. Ask your boss what to read on this topic or request them to name their 'favorite book'. You will surely hear the names Goldratt, Adizes, […]
The long-awaited day has finally arrived when I can present this development. The project was started exactly one year ago, on September 1, 2018; at least in the RRS repository on GitHub, the first commit has that date. Passenger train at Rostov-Glavny station (clickable) What is RRS? It is an open cross-platform simulator of 1520 mm gauge rolling stock. […]
Let's consider a scenario where it's necessary to ensure the safety of a bank vault. It is considered absolutely impenetrable without the key that you receive on your very first day of work. Your goal is to securely keep the key. Suppose you decided to always keep the key with you, granting access to the vault as needed. But you'll quickly realize that this solution doesn't scale well in practice, […]
Hi! My name is Pasha Chernyak, I'm the lead developer at QIWI, and today I want to talk about the inevitable. About Legacy. Let's start with the question: what is a Legacy service? Is it a service that the developer hasn’t touched in a week/month/year? Or is it a service that was written by a less experienced programmer, such as you specifically, but a year ago? And now you're better and […]
I had a 'home server' on Linux just a few years after I got my computer. Now, more than fifteen years have passed since then, and for most of that time, I've had some sort of second computer at home. One day, when it was time to upgrade it, I thought: why do I need a separate router when I already have […]
After a month of attempts and 252 deaths, YouTube user Super Louis 64 successfully completed Halo 3 on legendary difficulty using only a Guitar Hero controller. In a 22-minute video, Super Louis 64 showcases highlights from his Halo completion. It mostly consists of deaths that occurred before he could reach his impressive goal. […]
Version 7.0 of the SU2 project has been introduced — an open solver for Navier-Stokes equations. Change log: a new nonlinear iteration controller for improved robustness and convergence; enhancements for the lift force calculation mode (Cl=const); new features for Discrete Adjoint; a report on the quality of the computational grid; a "dry run" launch capability to check the operability of input files; modifications for the SST turbulence model; changes in […]
The most interesting thing that has happened to the writing profession over the last couple of decades is the so-called "online literature." A few years ago, writers gained the opportunity to earn money from their literary work without the mediation of publishing houses, working directly with readers. I briefly discussed this in the article "Writers Pro«. In this regard, one can only repeat after the son of a Turkish subject: "A dream came true […]
Not long ago, we implemented a solution on a Windows terminal server. As usual, we created shortcuts for employees on their desktops and said — get to work. But the users were quite intimidated by Cybersecurity. Upon connecting to the server and seeing messages like: "Do you trust this server? Are you sure?", they panicked and turned to us — is everything okay, can we […]
